Airborne Environmental DNA Analysis as a Tool to Monitor Live Bird Trade
Environmental DNA, Volume 8, Issue 2, March/April 2026.We explore airborne environmental DNA (eDNA) analysis as a novel tool to detect avian species and assess its potential for monitoring bird trade. We collected airborne samples in both enclosed and open market environments, accompanied by visual surveys, and processed them using DNA extraction and metabarcoding to identify avian taxa.

Wildlife Biology, Volume 2026, Issue 1, January 2026.During the 18th and 19th centuries, bird feathers (class: Aves) were harvested from wild populations and sold globally in enormous quantities to meet the rising demand of the fashion industry. Although many laws now prevent similar widescale harvest, there is a paucity of studies on the trade that has continued to occur since the 20th century.
